ok ... problem solved. No need for a xhtml file. I keep all code as initially described in the first post but, instead of using the tld descriptor, I use the xml one as this: <?xml version="1.0"?> <!DOCTYPE facelet-taglib PUBLIC "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN" "facelet-taglib_1_0.dtd"> <facelet-taglib> http://www.xxxxx.com/jsf <tag-name>div</tag-name> <component-type>javax.faces.Panel</component-type> <renderer-type>com.xxxxx.framework.view.jsf.components.Div</renderer-type> </facelet-taglib> and the reference on web.xml: <context-param> <param-name>facelets.LIBRARIES</param-name> <param-value> /WEB-INF/xxxxx.taglib.xml </param-value> </context-param> Thank you all for your help.
